Do you need special fabric for cross stitch?
The fabric used for cross stitch is usually aida or Evenweave/linen (these two come in the same counts but are made of different materials; Evenweave is cotton and modal and obviously linen is linen). These fabrics are perfect for cross stitch because they are weaved evenly.
How do you cut linen in cross stitch?
Save yourself the trouble of trying to salvage months of work and just give yourself a little extra room when cutting your fabric. When cutting your fabric before stitching, cut in straight lines. If the edge isn’t straight, the shortest edge will be what counts when framing and finishing.
